DUMPING-CAR.

Specification of- Letters Patent.

Patented Sept. 1, 1908.

Application filed February 13, 1908. 8erial No. 416,674.

T all whom it may concern:

Be it known that I, RICHARD H. STEVENS,

of Munhall, Allegheny county, Pennsylvania, have invented a new and useful Imwhich the body portions of the cars are arranged to be tipped in opposite directions to be emptied of their contents, and it more particularly relates to tipping ladle cars em- .ployed' in carrying molten metal, slag and similar materials.

The object of the invention is to provide improved means for holding or maintaining the car-body or ladle in its vertically upright position upon the frame of the car and for rocking or rolling the car bodyforwardly on its supports as it is tilted in being emptied of its contents.

In thedrawings 2 represents thecar frame of a dum ing ladle car which is mounted upon whee 'trucks'3 in the usual manner and 4 is the ladle which is removably secured in the trunnion ring 5 by means of bolts 6.-

The trunnions forming part of the trunnion ring 5 are provided with trunnion gears 7 whlch are eyed or otherwise secured in place. The trunnion gears 7 are mounted on racks 8 forming part of the car frame 2 so as to lpermit of the ladle being rocked sidewise in 0th directions to beemptied. The gears 7 are provided with teeth 9 which mesh with similar teeth 10 in the racks 8, and these gears are also provided with a c lindrical ace portion 11 which contacts wit the flat plane surfaces 8? on the racks 8 to support the ladle and prevent its weight bein put u on the teeth of the gears 7 and rac lrs 8.

ach of the gears 7 is provided witha horizontal flat portion 12, this flat portion being provided to maintain the car body in a vertically upright position, while being carried from place to ace upon the rails of a railwaytrack. are 13 are provided on each side of the car body or ladle to which a chain departing from my invention.

hook is secured for the purpose of tip ing the ladle to empty it of its contents. he cars are provided with the usual coupling devices and coupling operating mechanism.

In the operation of m improved car, the fiat sides provided on t e trunnion gears 7 hold the ladle stationary in its vertically upright position and prevent its being tipped w lo the car is being transported from place to (place upon the railway tracks. When it is esired to dump the car, a chain hook is attached to one of the ears 13 on the ladle 4 and the car is tilted or tipped through this hook and its chain, which is connected to an suitable means for dumping. As the ladle 1s tipped, the axis of the trunnion is raised vertically by the action of the periphery of the ear wheels 7 and at the same time the car ody or ladle is rolled forwardly or rocked by means of the co-acting teeth in the wheel 7 and the racks 8.

When the car has been emptied, the move ment of the ladle is reversed and the car is again brought into its vertically lfilfll ht osition, in readiness to be a ain le a ter which the above describe operations are re eated.

lhe advantages of my invention will be apparent to those skilled in the art. The aparatus is simple and is easily kept in repair.

here are no moving parts which have to be moved into and out of position to hold the car in its verticallyupright position and the car is securely held in this position while hein transported from place to place.

, odifications in the construction and arrangement of the parts may be made without Instead of having a'fiat surface on the trunnion gears 7,

these gears may be cylindrical and corresponding cylindrical depressions be provlded in the racks 8 so as to hold the car in its vertical position, or cylindrical trunnion gears having their-axis eccentric to the axis of the trunmons may be used with the straight rack 8 shown. While .I have shown my invention applied to a tipping ladle car, the invention is applicable enerally to tiltin cars havi a adle.

or be y portion which is tip ed eit or side- 105.: wise or endwise to empty it 0 its contents.

I claim:

1. In a ladle car, a rolling and tipping ladle having supporting trunmons gear wheels v on said trunnions, a car frame aving llOl'lzontally extending trunnion supports on which the trunnions roll in tipping the ladle, the contacting surface of the trunnion wheels and trunnion su ports having meshed gear teeth, the teeth of the trunnion wheels in contact with the trunnion supports when the ladle is in its upright position being flattened to lower the horizontal axis of the trunnion; substantially as described.

2. In a ladle car, a rolling and tipping ladle having a supporting trunnion, gearwheels on said trunnions, a car frame having horizontally extending trunnion supports on which the trunnion wheels roll in tipping-the ladle, the gear teeth on the trunnion wheels in mesh with therack teeth on said trunnion supports being arranged to lower the axis of W.
